工程图中基准代号自动标注的ARX二次开发

Development of AutoCAD on Automatic Labeling Base Symbol Used ARX

针对在AutoCAD2000中标注位置公差时,没有直接标注基准代号的命令这一不足,利用Visual C++6.0,在Auto-CAD2000环境下,开发了一个基准代号自动标注的ARX应用程序。论述了编程原理,并对基准代号的生成、基准符号方向的判定、字母的插入等关键问题进行了讨论。给出了标注实例。该技术已用于某机械设计CAD系统中。

Using the tools and platforms such as Visual C ＋ ＋ 6.0, ARX, this article develops an AutoCAD application on labeling base symbol. The principles of program are discussed. Many key techniques are resolved, such as the methods of building symbol, inserting text. The application is also illustrated by some related instances and it has been used in a CAD system of machine design.
